Comment 14 for bug 1976198

I myself also don't feel strongly in this particular case. Normally I don't want to release pure-FTBFS fixes for no good reason, but here I'll "Just Do It™" because I'm worried I'd forget about it before the point-release. Point releases have a lot of moving parts, so it's easy to miss out small things like these. Plus, 2MB of additional size should be bearable for libsdl2 consumers.
